This paper proposes a micro-strip patch antenna operate on the dual frequency bands. The proposed antenna design consists of U slotted patch with direct coaxial probe feed technique. The U slotted patch offers a low profile, high gain, broad band and compact antenna. The proposed designs are based on patch loaded with U slots in the form of cut from the sides and center of the rectangular and circular patch. Details of the design considerations of the proposed antenna are described, and simulated results of the obtained dual-band performances are presented and discussed. The method of computation uses MOM and this is simulated by using HFSS software.
